160 A MCCB with ETU320 — current production, panel-ready
Four poles, line protection version, fitted with the ETU320 electronic trip unit. The 440 kA interrupting rating at 240 V (330 kA at 415 V, 220 kA at 500 V, 53 kA at 690 V) gives substantial SCCR headroom for most industrial distribution panels without needing a current-limiting upstream device.
The ETU320 release is an electronic trip unit with adjustable long-time pickup and delay (tr adjustable from 0.5 s to 17 s). Neutral protection configurable: OFF, 50%, or 100% of phase rating. No ground-fault monitoring on this version — if that's needed, you'd step to a variant with the G option.
